Today Microsoft announced the latest addition to the next Minecraft major update for the following editions (Windows 10 Edition beta, Pocket Edition and the Gear VR Edition) , called the Boss Update. This fearsome update is packed with content that is sure to thrill every type of Minecraft player, with two big new boss battles, new blocks for building and even the first set of long-awaited slash commands for those who love to tinker with the game.

Survival players are in for a real treat with the Boss Update. Ocean Monuments will be discoverable, and you can enjoy adventuring in these new, rare locations with friends beneath the sea. Get ready to fight through the Elder Guardian boss and its squad of Guardian sea creatures with laser beams attached to their heads, conquer underwater enclaves and loot their treasures.

The Wither boss battle will also be available to Minecraft on mobile and Windows 10 with the Boss Update. The Wither boss is a powerful, floating, three-headed mob who is clearly up to no good. You can summon and defeat this mob in order to claim the ultra-rare nether star item that it drops. Nether stars can then be used to craft beacons, unique blocks that can project a beam of light into the sky and can provide helpful status effects to players in the area.

Creative players will benefit from the ability to use new blocks in their creations from the introduction of these new gameplay features – they’ll be able to light up their creations with beacons and sea lanterns, build with prismarine blocks and decorate with sponges.

Lastly, the long-awaited first set of slash commands will also be available in this update. Slash commands allow you to make quick changes to the game without utilizing a menu – give other players things from your inventory, summon a mob at your will, change the time of day or weather, swap back and forth between survival and creative modes, and more! There are over 20 slash commands included in this update, with more to come in the future.

The Boss Update will be out as a free update for all owners of Minecraft: Windows 10 Edition beta, Pocket Edition and Gear VR Edition this fall.
